UNSOLVED
I am using two different Nvidia 8800GT through SLI and did not notice a difference
I purchased an xps 630 with only one nvidia 8800GT and wanted to get another one. So I called dell and they send me the sli bridge and a totally different card, it does not look like the one I first got. They mentioned that the ones they send with the pc, are specially made for dell. So I went ahead and installed the card with SLI bridge and did not notice any difference on the games (BioShock, World in Conflict) . Is it because one is already overclocked? I did go to the nvidia control panel and notice that they are set to the same settings. On the system montitor there is a difference on the BFG that one is running a bit higher. Any help would be greatly appreciated. Don't know if this will help but I have not overclocked the original video card.
XPS 630
Intel® Core™2 Q6600 Quad-Core (8MB L2 cache,2.4GHz,1066FSB)
3GB Ram
(1) Nvidia 8800GT Core Clock - 600MHZ, Shader Clock:1500
(2)BFG Nvidia 8800GT OC - Core Clock:625MHZ, Shader Clock: 1566
Windows XP Pro
did you enable SLI in the Nvidia control panel?
Also how are the cards reported..are the both reported as the same type ie..8800gt's?
They will work with different mfrs as long as they are the same card flavor..
Also SLI does not offer that great a difference in game performance..

I actually tested this. In Call of Duty 4, I get an increase of close to 10 FPS with dual video cards enabled in the game. So yes, it does make a difference but the game needs to support it.
And you can really see this diffence??? anything over 20FSP the eyes cannot really process. But from a performance standpoint and bragging rights you are correct..
Just to me a small increase in frame rates does not justify the cost of another video card. My .02 :smileyhappy:

I'd probably have to play them side by side to actually see the difference, and I guess a "small increase" will be different to different people. I just noted the actual FPS in the game to see if there was a difference. But a 10FPS increase is nothing to sneeze at, and will likely help with any lag issues. I'm actually going to test this out with Crysis soon as well, and see how SLI helps there.- I can easily tell the difference between 30fps and 45fps, in fact much below 45 and many games make me nauseous. I'll go one step furhther and say that SLI can make a huge difference, it isn't just about frame rate but about how many detail slider, AA and AF settings you can crank, which anyone can see. And of course, you need to play at (the very least) 1440x900 to really get something out of it. I prefer playing at 1680x1050 so i am really looking forward to SLI.
Thanks to everyone that replied, another thing that I wanted to add is that I have the comp connected to a Sony 40inch Bravia at 1024X768 would this matter. Also do I have to OC my first card to have it running the same as the one I just got. Thanks Again.

Actually it's 24fps :smileywink: but otherwise you are absolutely correct.
There is more to fps in games than what you see on screen. All quake base game configs can be edited to get a lot more fps than default, which for COD4 is 85. That is the reason leagues that use CAL/CEVO/TWL PunkBuster Config have this in it "pb_sv_cvar com_maxfps IN 30 250", that sets max rate to no higher than 250 fps. With 2 8800 gtx cards in sli players can and do run 1000fps on pub servers. Read this for what high fps can do for a game, there is lot more than just this tho. This link was for cod1, but it works for "all" quake based game engines. My fps it set to run at 250fps all the time with single 8800 gtx card.

crank the resolutions up on the tv as high as they can go and then in the game settings and the nvidia control panel make them the same i have a samsung 32 inch lcd tv and my resolutions are set at 1360x 768 which are the highest the tv will support and i set all my game resolutions at the same. your picture will black out if u set them other than what the tv will go .u will see a big difference in the sharpness of the image. one other thing only set the game resolution settings at the different resolutions the tv supports or you wont get a picture look in your tv setup to see what resolutions it supports.
